Might as well do all breathing mods and a pcm just in case you decide you want boostay later.
-CAI (not HAI)
-180* t-stat
-Down pipe w/ u-bend delete
-plog or headers ( if you get headers you won't need the downpipe or u-bend delete)
-intense shift kit (you don't have to but it helped a bit with upshift & downshift)
-A PCM reflash. either do it yourself with HPtuners or overkill or intense pcm.
